I bought this unit to replace my Fog Fury Faze which died. I have to say that this unit is superior to the Fog Fury, simply due to the level of control you have over the smoke output. Be under no illusion, this IS a smoke machine, but the controls on the unit allow a very fine control of output, from 1% to 100% smoke (a little to a lot) and this combined with the timing options for interval between smoke output and duration of smoke production means that you can tailor output to just enough. The unit does clean pipes too, which hopefully will prolong the life of the heater element - there are specific instructions in the manual around this. The flap at the front allows you some control over the direction of output from directly ahead to almost 90 degrees up in the air which is useful and the unit can also be mounted overhead using the bracket, although I always use smoke machines at ground level from a safety point of view. The unit functions very well and adjusting controls will allow you to refine for every venue. There is one weak point and that is the fluid / pipe connector on the front of the fluid reservoir. This is exposed and highly vulnerable to to catching something in transit and breaking off - you have been warned. Obviously with care in transport and use you should be fine. I can't find a suitable flight case at a sensible price for this unit to help with protection in transit, similarly I wouldn't want to transport in a soft bag due to the risk of the reservoir connector getting broken! One other issue that surprised me was the captive power supply and no IEC connection, this somewhat limits positioning, but if you remove the plug and fit a male IEC on the end that should suffice - but will probably invalidate the guarantee! I am happy with this purchase, the control over output is very good, but the product loses one star due to the exposed delicate reservoir connection and the captive power supply. Apart from that it's a great unit.
